Earth to lose its Blue colour by 2100

Environment
Blue Earth from Outer Space

Climate Change will alter the way our planet looks in the future. Our future generation might not see the planet as we do. The rising temperature levels are disturbing the distribution of phytoplankton in oceans throughout the world. These microscopic creatures are so minute you won’t be able to see them with your naked eyes but their change will be seen even from the space.

Global warming will change the colours of the oceans that’s according to a new study published by MIT Researchers in the journal Nature Communications. They developed a model and simulate a possible outcome in the future using Satellite Images. These images helped Researchers to analyse the rise of global temperatures and they were able to predict how the growth and interaction of phytoplankton will change the colour of the oceans around the world.

The study also confirms the data analyses from so many other studies that global warming will wipe out most marine life and they will also drive the phytoplankton population in the Subtropical Regions. In these areas, the blue colour of the water will be more intensified. Climate change will also affect the Water closer to the poles and the phytoplankton population will be more diverse. The reflected Sun rays from these microscopic organisms will change the Green colour and make it more intensified than before.

The Reflected Sun rays determine the colour of the oceans. The Water Molecules absorbs a majority of the light Spectrum(VIBGYOR) exception of the Blue Part. This Exception is the reason why the barren oceans look blue and the phytoplankton in the water absorbs and reflect some light and hence we see green colour in some areas of the ocean.

This Research was unique in a way because it was based on reflected light measurements. This new model helped scientists to examine the phytoplankton population behaviour in the future. In previous models were based on estimates of chlorophyll(found in phytoplankton). These Models didn’t reflect any significant changes due to a finding that suggested chlorophyll were only reflecting the ocean currents but it is unable to indicate the changes due to climate change.

One of the researchers explains that climate-related shift will show a significant change in the future. They are looking for a satellite measurement for a real signal of change.

These Simulations helped the researchers to predict that a noticeable change will alter the colour of the globe. The colour of nearly half the planet oceans surface will change by the end of this century.
